Docker Image for JVM platform contains fixed JVM 8 by default

[tpasternak]

This causes runtime failure, if a user builds. code to jvm 11

so the app in image built with scala-cli package --docker --jvm 11 will fail to start

We should probably change that depending on --jvm. At least default to openjdk 8 / 11 / 17 images, picking a version higher than or equal to the one of the JVM passed via --jvm when possible.

We might also check if there are specific docker images for specific JVMs (zulu, graalvm, etc.), although that looks a bit like an overkill…

It's now bumped to jvm 11, closing for now
